Possibility of rearranging Flight-Modes in Companion by drag'n drop - autoupdating all dependencies (in mixers etc.)

Which board (stock / gruvin9x / sky9x / Taranis) are you using? Taranis

What is your openTx FW version?  2.12

What is your openTx EEPROM version?  I dont know - I haven't used a Tx yet.

What steps will reproduce the problem?
1. Create some Flight Modes and some mixers dependent on these
2. If you realise you need to rearrange Flight Modes as they are prioritized 
(just found out today after having created a model with more than 18 lines of 
mixers used.
3. In the present state of Companion, I need to reenter the names of flight 
modes in the priotized order, and manually re-check all related flight modes 
used in every single mixerline. This is too stressfull.
4. An apparant solution would be to make the Flight mode name-tabs on the 
Flight mode tab dynamic, so they could be dragged and rearranged in a new 
priority order. Obviously all dependencies should auto-update, so you didn't 
need to go through them all manually afterwards. 

This would help immensely when designing complex models.

What is the expected output? What do you see instead?

Please provide any additional information below.
